I kind of jump to conclusions sometimes. Like if they have an anime girl as their profile pic and they don't have their gender on their profile then I assume that they're a guy. Other than that, that's really the only judging I do.

Yes and no. I judge them on their sign and sometimes what they say in their profiles, which I believe says a lot about your personality - but if their picture is one of them that's really glamorized, it's not usually a good start.
